Abstract: A method comprises capturing a first signal from a first radio chain, and dividing samples of the first signal into a first set of sub-vectors. A second signal is captured from a second radio chain. Samples of the second signal are divided into a second set of sub-vectors according to the determined mapping pattern. A gain difference and phase difference between each sub-vector of the first set and a sub-vector of the second set are estimated, acquiring gain differences and phase differences of the first signal and the second signal. The sub-vector level gain differences are combined to acquire a gain difference between the first signal and the second signal. The sub-vector-level phase differences are combined to acquire a phase difference between the first signal and the second signal. One of the first radio chain and the second radio chain are configured to reduce the gain difference and phase difference.

Abstract: Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.

Abstract: A CPU implements a virtual network function (VNF) associated with flow processing and can offload at least some of the flow processing to a hardware accelerator. A module (e.g., TOR switch), external to the software-based processor and the hardware accelerator, examines packet flows and determines (e.g., using a top-K elephant-flow-detection algorithm) which ones are more suitable for offloading from the software-based processor to the hardware accelerator than others. The external module communicates the relative suitability for offloading to the CPU using packet tags or out-of-band messaging, and the CPU uses the relative suitability to determine which flows to offload or onload. In some implementations, the CPU can instruct the external module to change the value of K used in the algorithm.

Abstract: An upstream (US) optical line terminal (OLT) for a passive optical network having at least one downstream (DS) optical network unit (ONU). The OLT generates a trigger signal indicating a need to receive at least one US burst having a shortened codeword for a first forward error-correction (FEC) code. Based on the trigger signal, the OLT transmits a DS message instructing the ONU to transmit an US burst having a shortened codeword. The OLT receives and decodes the US burst having the shortened codeword using the first FEC code. During periods of high bit-error rate, the shortened codewords increase the ability of the OLT to decode the US bursts and keep communications from the ONU alive. The OLT can use the decoded US bursts to measure BER and, if appropriate, instruct the ONU to use a different FEC code.
